Tell us what’s happening:
Describe your issue in detail here.
I thought that this is what the question meant and I have tried so many variations but it still keeps telling me to nest my new div elements within the container one. What am I doing wrong? Please can someone help me here, I thought I finally understood it.

  **Your code so far**
/* file: index.html */
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Colored Markers</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <h1>CSS Color Markers</h1>
  <div class="container"><div class="marker"><div class="marker"><div="marker"></div></div></div></div>
  
</body>
</html>
/* file: styles.css */
h1 {
text-align: center;
}

.marker {
width: 200px;
height: 25px;
background-color: red;
margin: auto;
}

behind the opening tag, you gave the
last div 4 closing tags in your code.

element multiple times:
Select what you want to copy, in your case
<div class="marker"></div>",
then press and hold shift and alt
press the down arrow as many times as you need,
in this challenge two more times.
